Description
Technical Field
[0001] The utility model belongs to the technical field of automobile production technology, and specifically relates to a locking device for a plate. Background Art
[0002] With the continuous improvement of living standards, people's demand for means of transportation is growing, and the diversification of customer needs has led to an increasing amount of automobile production in my country's automobile industry, followed by the globalization of vehicle production competition. In this case, manufacturers have to shorten the production cycle of automobiles to balance the supply and demand relationship. In the production and manufacturing workshop of automobiles, conveying equipment is often needed to improve production efficiency and reduce manufacturing costs. Usually, the efficiency of man-machine combination is very high, and workers will use conveying equipment to assist robots to complete the welding work of automobiles, thereby speeding up production efficiency. As far as the current situation is concerned, in the process of equipment transporting panels, the position of the panels when welding to each working point must be accurate. Otherwise, the position of the welding point and the welding point of the welding gun walking track will deviate from each other, which will lead to problems such as scrapping of the panel or low efficiency, so it is very necessary for us to understand and use this equipment. It is necessary for us to improve such a structure to overcome the above defects. Utility Model Content

[0015] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0016] like Figure 1-4 As shown, a locking device for a plate comprises:
[0017] A mounting plate 1 is provided on the mounting plate 1, a pulley 2 is provided on the mounting plate 1, a small rotating shaft 3 is installed in the middle of the pulley 2, a roller guide assembly 4 is provided above the pulley 2 to fit with it, a rotating shaft 7 is installed in the outer sleeve 5, wherein a sleeve 12 is provided between the outer sleeve 5 and the rotating shaft 7, a flat washer 13 is provided on the outside of the mounting plate 1 connected to the rotating shaft 7, a cotter pin 9 is provided on the outside of the flat washer 13, wherein the cotter pin 9 passes through the rotating shaft 7, a block 14 is provided on the right side of the block mounting frame 6, a washer 8 is provided on the outside of the pulley 2, a cotter pin 9 is provided on the outside of the washer 8, a spacer 10 is provided on the inside of the pulley 2, the spacer 10 is fit with the telescopic rod of the cylinder 11, wherein the small rotating shaft 3 passes through the cylinder 11.
[0018] The mounting plate 1 is composed of 5 steel plates, which are 1 large rectangular steel plate placed horizontally; 2 small rectangular steel plates welded to the large rectangular steel plate, placed horizontally; and 2 medium rectangular steel plates welded to the large rectangular steel plate, placed vertically.
[0019] The roller guide assembly 4 is composed of an outer sleeve 5 and a stopper mounting frame 6 .
[0020] The stopper 14 is rectangular and is fixedly connected to the stopper mounting frame 6 of the roller guide 4 .
[0021] The pulley 2 moves left and right along a track with a small rectangular steel plate placed horizontally in the block mounting frame 6 in the roller guide 4 as an upper track and a rectangular plate placed horizontally in the mounting plate 1 as a lower track.
[0022] Two cotter pins 9 pass through the small rotating shaft 3 and the rotating shaft 7 respectively to play the role of fixing, locking and preventing falling.
[0023] The cylinder 11 is fixed on the mounting plate 1 , and the end of the telescopic rod of the cylinder 11 is penetrated by the small rotating shaft 3 .
[0024] The small rotating shaft 3 passes through the two pulleys 2 and the end of the telescopic rod of the cylinder 11, wherein the telescopic rod of the cylinder 11 is located between the two pulleys 2.
[0025] The rotating shaft 7 passes through the outer sleeve 5 in the roller guide assembly 4. The roller guide assembly 4 is located between the vertical rectangular steel plates in the mounting plate 1.
[0026] like Figure 1 As shown, when the cylinder is inhaled, the cylinder telescopic rod moves to the right. At this time, the small shaft drives the pulley to roll with the mounting plate and the block mounting frame as the track. The block mounting frame is supported by the combined force and the direction remains unchanged. The roller guide and the block are both stationary. At this time, the device is in a locked state. When the plate is transported to a fixed position, it will be locked and limited by this device; when the cylinder is discharged, the cylinder telescopic rod moves to the left. At this time, the small shaft drives the pulley to roll to the left with the mounting plate and the block mounting frame as the track. When the pulley moves to the groove of the block mounting frame, the force support point of the block mounting frame moves downward, causing the roller guide assembly to drive the block to rotate downward. At this time, the device is in an open state. The pulley moves with the mounting plate and the block mounting frame as the walking track.
[0027] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
